Throwing C++ exceptions across DLL boundaries

by

Throwing C++ exceptions across DLL boundaries is only possible when all modules use the same C++ runtime, in which case they share a heap as well. But this can be a maintenance burden, especially when libraries from multiple vendors are involved, so it is discouraged.

If you want error-handling which is portable across multiple compilers/compiler versions/compiler settings, either use return codes or OS-provided exceptions (e.g. SEH on Windows)/
